High Availability Support for AirWatch Components

<

Application servers receive requests from the console and device users and process the data and results. No persistent data is maintained on these servers, but user and device sessions are maintained for a short time.

High availability is achieved by using load balancing and session persistence. See Monitoring for information on health checks on the servers. The following table outlines both for each AirWatch component:

Contact AirWatch if you have specific questions or concerns about your specific deployment.

Timeout Value

Console

Yes*

Source IP-based persistence

60 minutes

*The Scheduler and Directory Sync services must only be active on one Console server. All other services/endpoints of the Console can be load-balanced in an active-active configuration.

Device Services

Yes

Source IP-based persistence

20 minutes

AirWatch Cloud Messaging

Yes

Persistence based on parameter awcmsessionid in either the URI or HTTP Header.

*Persistence is not required if the short-lived TCP connections are not interrupted while they are active.

VMware Tunnel (Proxy)

Yes

Source IP-based persistence

30 minutes

Secure Email Gateway

Yes

Source IP-based persistence

Configure to be the same as the persistence timeout value for your Exchange ActiveSync Servers based on recommendations from the Mail Solution vendor.

Content Gateway

Yes

Not required

N/A

Remote File Storage

Yes

Not required

VMware Enterprise Systems Connector

Not required (see Note)

Not required

N/A

API (SOAP and REST)

Yes

Source IP-based persistence

Note:

VMware Enterprise Systems Connector traffic is automatically load-balanced by the AWCM component. It does not require a separate load balancer because there are no incoming connections. To accommodate extra users as part of your sizing requirements you can deploy multiple VMware Enterprise Systems Connectors, which are all load balanced by AWCM.
